Patent CA-2194710-A1 (CA)
Inventor: DOBBINS BOB M
IPC: G07D5/00
Filed: 1991-10-09
Abstract: Methods and validation apparatus for achieving improved acceptance and rejection for coins, bills and other currency items.  One aspect includes the steps of sensing data characteristic of at least two characteristics of each of a plurality of genuine items representative of the universe of items to be validated; converting the sensed data into a plurality of vectors for each item type and storing the vectors in a look-up table in memory.  The method then calculates a mean vector for each item type and tests an item and generates a vector corresponding to the characteristics for the item.  A difference is calculated between the item vector and the mean vector for an item type.  This difference is compared to a first mean vector tolerance and an item denomination index is then incremented.  The difference is recalculated and compared to a mean vector tolerance for another item type if the comparison did not fall within the first mean vector tolerance.  If the difference falls within the corresponding mean vector tolerance then an item type look-up table is searched.  The item will be ultimately accepted if its vector is found in a look-up table, and rejected if its vector is not found.

Title: Unlocked w-band receiver with coherent features
Inventor: KENNEDY THOMAS A
IPC: G01S13/00
Filed: 1997-05-15
Abstract: A coherent radar receiver that has pulse-to-pulse coherence using an unlocked voltage controlled oscillator, such as a Gunn voltage controlled oscillator. The present invention is a W-band, for example, bistatic receiver that uses a scanning sum channel antenna to scan the target, a downconverter for downconverting received alternating sum and difference pulse echoes from the bistatic illuminator to provide video signals, and processing circuits for processing the downconverted the video signals to precisely locate the null position on the target. A Fourier transform circuit, magnitude detector and a peak detection and centroid circuit are used to generate a voltage frequency control output signal that is applied to the voltage controlled oscillator or local oscillator that controls its frequency. An angle estimation algorithm is used that processes the video signals to locate the null offset from the center of a scan pattern generated by the antenna. The present invention thus provides for an inexpensive weapon receiver at W-band, for example, using an inexpensive unlocked voltage controlled oscillator. The pulse-to-pulse coherence achieved by the receiver permits precise location of a target of interest from bistatic radar returns.

Title: Low emissivity, high reflectivity insulation
Inventor: AANESTAD RANGVALD
IPC: F16L59/08
Filed: 1997-07-25
Abstract: A multi-layer flexible insulation comprises a series of layers which include a pair of closed-cell insulation sheets made of multicellular plastic film (i.e. closed cell air bubbles or bubble-pack) and laminated on both sides of a thin white polyethylene film, a pair of aluminum foil layers or films adhesively mounted on the outer surfaces of the bubble-pack insulation sheets, and a thin clear polyester layer provided on the outer surfaces of the aluminum layers. The aluminum layers are vapor deposited on the polyester layers and are assembled to the hot bubble-pack insulation sheets while the latter are cooled. The bubble-pack sheets are then adhered to the central polyethylene film with a hot melt glue. If the polyester is highly smooth, the aluminum can be deposited thereon in a uniform state thereby providing a high reflectivity, low emissivity, laminate. The outer polyester coatings also protect the aluminum layers such as to prevent any aluminum from rubbing off the insulation and also prevent the aluminum layers from oxidizing. Furthermore, the polyester coatings provide an hygiene barrier for the insulation.

Title: Mos charge pump generation and regulation method and apparatus
Inventor: TRAN HIEU VAN
IPC: H02M3/07
Filed: 1997-09-30
Abstract: MOS charge pump generation and regulation method and apparatus of the general type used in a non-volatile memory chip for generating high voltages (~20v).  This invention utilizes a current controlled oscillator to generate the clock for the charge pump voltage multiplier.  The oscillator frequency is designed to compensate for process, temperature and power supply variations.  The charge pump shunt regulator only utilizes regular low voltage NMOS and PMOS from a standard CMOS process.  A reference voltage scheme is used in which a regular low voltage PMOS is used as a mirror diode (reference PMOS) to precisely realize a control voltage for the shunting NMOS without violating any breakdown mechanism, i.e. PMOS gated diode breakdown and P+ to n-well junction breakdown.  A medium voltage level is also used to buffer the shunting NMOS transistors from gated diode breakdown.  A native NMOS cascode current mirror is used to precisely mirror the current to achieve minimum headroom voltage with minimum circuit area.

Title: Method and apparatus for detecting tube occlusion
Inventor: BLYTHE ROBERT LEWIS
IPC: A61B18/00
Filed: 1998-01-30
Abstract: A method and apparatus (10) detect occlusion in a tube to a passage into a body cavity. An argon gas supply output (13) received by plural selectable flow orifices so one or more of the orifices delivers predetermined metered gas. A duct (16) with a volume of gas selectively provides metered gas to the passage. The tube connects the passage and the duct (16) periodically so a duct (16) pressure transducer (17) can signal. A circuit tests signals of tube equalization with a back pressure. A three way valve controlled by the circuit connects the duct (16) transducer to gas metered to the cavity. The valve alternatively connects the duct (16) transducer to the tube to equalize the tube with metered gas to the back pressure. A monitor (20) of the signals determines the rate of pressure change after the valve connection The monitor (20) indicates pressure equalization after a timed interval with a timer to establish intervals for checking back pressure. The monitor (20) remembers cavity pressure before connecting the duct (16) transducer to the metered gas and compares remembered pressure with the back pressure after each test interval. Plural orifices provide specific gas flows to the handset and the valve for equalizing them with metered gas as a function of the flow. Connecting plural orifices to meter gas output, delivering the metered gas output with one or more of the orifices, containing the volume of gas in the duct (16) connected to the metered gas output, selectively connecting the duct (16) to the passage, connecting the tube to the passage with the duct (16) and the transducer to periodically signal are steps. Coupling the circuit to one or more orifices, equalizing the tube with back pressure in response to the signals and coupling the transducer to the metered gas output are steps. Connecting the duct (16) transducer to the tube permits periodic back pressure equalization with metered gas output, signaling the monitor (20) with the transducer, determining periodically the rate of pressure change in the tube by the transducer, indicating in the interval with the monitor (20) equalized tube pressure and remembering cavity pressure before connecting the metered gas output and the transducer for intervals and providing specific flows to the handset and the valve to make the back pressure a function of the selectable flow are steps.

Abstract: An optical filter is provided having first and second graded index (GRIN) lensespreferably disposed in a coaxial relationship so that they have a common optical axis. Each of the GRIN lenses have an endface providing a port at predetermined location. The ports are disposed on opposite sides of the optical axis and each of the ports are substantially equidistant from the optical axis, so as to be oppositely offset from the optical axis by a same amount. The filter also includes an optical interference filter disposed between other endfaces of the first and second graded index lenses. By changing the location of the ports by a same small amount, the center wavelength of the filter changes by a small amount, thus in manufacture, the filter is tunable. After tuning the filter to a desired wavelength, the locations of the ports are fixed.
